2014 Safety at Sea, USNA * Note items in “red” …you will need that information later! Fuel Heat And a Chemical chain reaction Remove one of these, and you can put out a fire! Oxygen Materials which leave an Ash: Wood, cotton, fiberglass, cushion, sails Effective extinguishers: Water (Caution – load limits!) Dry Chemical Carbon Dioxide Concerns: Fire may be deeply embedded in materials and require “overhaul.” Ok, what is overhaul? This was a covered marina made of wood! See the boats? BoatU.S. Insurance Flammable liquids (things that boil): Oil, gasoline, resin, paint, kerosene, diesel Effective extinguishers: Sodium Bicarbonate (baking soda, NOT flour!) Dry Chemical Carbon Dioxide Halon replacements Concerns: Water may spread the fire! Liquids with high flashpoint may re-ignite (keep covered to avoid vapor release) Would the fire extinguishers on your boat put this fire out? How hot is it on the bow of this boat…could you stand there? BoatU.S. Insurance Where would you go if this happened to you sailing offshore? Could you abandon your boat in two (2) minutes? BoatU.S. Insurance How would you get out of this boat if you were asleep in the v-berth? Do you think they had a smoke or CO detector? BoatU.S. Insurance Electrical Fires (shorts): Wire insulation and adjacent materials Tactics: Break circuit, turn off main switch (first step!), have circuit protection Then extinguish according to what materials are involved Water is not a choice on Class C fires Concerns: Shock hazard (is the power off – are you sure?) Shore Power Connections This is one of the most common types of electrical fires boaters experience at a marina. So, do you have a procedure to disconnect your shore power? Turn off dock’s breaker to the pedestal and then the main AC breaker in boat; 2) Unplug shore power at pier; 3) Disconnect the shore power from boat receptacle; 4) Reverse the process when hooking into shore power and remember to verify polarity. 1) Photo by - jbacchi BoatU.S. Insurance Fires caused by burning metals: Flares are the main concern Nickel Metal Hydride batteries also (examples are PlayStation devices) Tactics: Get it off the boat May use material to try to cool, isolate and smother Concerns: Does not play nice with water! 55% Poorly installed electrical systems (C) 30% DC shorts and wiring 12% DC engine voltage regulator 4% AC appliance/heater 4% AC shore power system 2% AC wiring/panel 2% DC battery charger 24% Engine and Transmission Overheating 19% engine overheating 2% turbocharger overheat 2% transmission overheat 1% backfire 8% Gasoline fuel leak 95% of fuel-related fires involve gasoline 1% Galley stoves Declining compared to when alcohol stoves were popular (this happened to me – alcohol stove fire) 12% Unknown or miscellaneous BoatU.S. Insurance BoatU.S. Insurance Sodium Bicarbonate Low toxicity Inexpensive Excellent for Class B Messy clean up Inexpensive Portables Tri-Class or Multipurpose Dry Chemical No worry about selecting the right extinguisher Forms a crust on Class A fires, making clean up challenging Need to turn upside down and shake it to loosen the power on a regular basis! Needs to be recharged at least yearly (even if not used)! Tri-Class Portable Carbon Dioxide Cools and suffocates Pretty ineffective - Large extinguishers! Leaves no residue Halon and its derivatives Halon 1211 and 1301 cannot be bought, but can be refilled Halotron 1 is a replacement Halotron Portables FM-200 Halon replacement Mounted in the engine room Heat causes “stinger” to burst Activated at 175 deg F From 25 to 150 cu ft Stinger FM-200 Have extinguishers located in all occupied spaces of the boat, cockpit, and the engine room. Fight a fire quickly; fires are virtually impossible to put out if given a head start. Fire volume can double every 7 seconds!!!! Use extinguishers to allow you to escape from below. How could you get out of every stateroom, head or compartment if the main hatch was blocked? PASS – Pull-Aim-Squeeze-Sweep (Aim extinguisher low at base of fire and sweep across base of flames.). Install extinguishers above floor - keep them away from water! Have a back-up person assist ; close at hand with the extra extinguishers! Use a flashlight and stay oriented; Stay low - avoid smoke (better visibility); Smoke kills more people in fires than actual burns. Do a dry run, with a knit cap and try to get out of your boat without using the main hatch. Have an exit plan! Have a fire escape plan and practice it; Install CO and smoke alarms in each compartment; Remember, CO is the silent killer! Change your smoke alarm and CO alarm batteries yearly (at least); Make sure everyone knows how to call for help; Have fire extinguishers readily available and make sure everyone knows how to use them. Questions? Ok, time to go outside and have some fun: 1) Fire Safety Trailer; 2) Electrical Short Simulator; 3) Fire Extinguisher Practical Exercise.
